When the diesel engine is started in winter, besides strictly following the requirements of the instruction manual, in order to improve the start-up performance, it is necessary to keep in mind that the “three suitable and four avoidable†diesel engine starts at low temperatures.
It is advisable to use “0†diesel oil: When starting the diesel engine in winter, the fuel system should be maintained for seasonal maintenance. Under normal circumstances, the “0†diesel fuel with a low freezing point should be used as fuel to ensure that the lowest temperature will not affect the use of solidification.
Second, hot water preheating: Before the start, add 60 °C ~ 75 °C hot water to the body, preheat the body, and can be used hot water injection pump, high pressure tubing and other preheating.
Sanyi should warm the oil in the sump: use the charcoal fire grill pan (disable the open flame) or put the oil into the container, put the container in water and add it again after heating.
A bogey start without cooling water: If you do not add cooling water at the start, and then add the cooling water after the diesel engine start, it will cause the temperature rise of the tank due to the sudden encounter of cold water and cause the body, cylinder head cracks.
Second, avoid blaze fire: heating the fuel tank with open flame will not only damage the paint on the surface of the body, but also easy to burn the plastic tubing, causing oil spills, and even an explosion due to the rapid expansion of gas in the tank, resulting in the destruction of the body and casualties; Bake an oil pan with an open flame will not only affect the service life of the engine, but also make the engine oil deteriorate and reduce the lubrication effect.
Third, avoid bogey fire start: smoke absorption advises to remove the air filter, so that the diesel engine into the air with fire. In this way, unfiltered air will accelerate the wear of cylinder liners, pistons, piston rings, valves, valve seats, etc., and often start by attracting fire. It will also increase the carbon deposit in the combustion chamber, which will reduce the service life.
4. Avoid preheating and use other powers to forcefully start: Diesel engine without warm-up, but with other power forced start, will make the crankshaft and the bearing between dry friction or string dry friction state, it is easy to cause the crankshaft to hold the tile.
